SSE (including brands Atlantic, Scottish Hydro, Southern Electric and SWALEC) have raised prices for 2014.
Latest price change
The price rise will impact all SSE's customers, and takes into account the supplier's original price rise of 8.2% announced in October 2013, and its subsequent price reduction of 4% announced in December of the same year.
The price rise went into effect 15 November, while the reduction will not be applied until sometime in March 2014.

What uSwitch say about the price rise
At the time of the announcement, uSwitch Director of Consumer Policy, Ann Robinson, urged SSE customers not to take the price rise lying down:
"I would also urge consumers not to sit back and watch energy costs soar. There are two simple steps to protecting yourself from the impact of higher prices: use less energy by making your home more energy efficient, perhaps by taking advantage of the Green Deal, and pay less for the energy you do use. There is now around £350 difference between the cheapest and most expensive energy tariffs on the market – this is a substantial saving and could make the difference when it comes to keeping warm."

SSE's price history
SSE's last price change came into effect in October 2012, when SSE customers had a rise in their bills of 9%, or £119 per year.
Scottish and Southern Energy (SSE) is Britain's second largest energy supplier and the first of the 'big six' suppliers to announce a price increase ahead of the 2013/2014 winter season. Southern Electric gas and electricity prices also went up, as did those of the Atlantic, Scottish Hydro and SWALEC.
